AT90PWM81
When the SPI is enabled, the data direction of the MOSI, MISO, SCK, and SS pins is overridden accord-
ing to
page
Table 14-1.
Note:
The following code examples show how to initialize the SPI as a Master and how to perform a simple
transmission.
DDR_SPI in the examples must be replaced by the actual Data Direction Register controlling the SPI pins.
DD_MOSI, DD_MISO and DD_SCK must be replaced by the actual data direction bits for these pins.
E.g. if MOSI is placed on pin PB2, replace DD_MOSI with DDB2 and DDR_SPI with DDRB.
